If you are the type of person who would shell out the extra cash for leather upholstery, you probably also want the best car leather cleaner and conditioner to keep it looking its best. Leather car seats cost a premium, but they return that investment in the form of higher resale values. Of course, that’s only if the leather is in great condition. To keep it clean and looking fresh, invest in a quality car leather cleaner and conditioner.
A Guide to Leather Cleaners and Conditioners
Car leather is almost always top-grain cow leather, meaning it includes the outermost layer of the animal’s skin. As such, this leather has a natural grain to it that is visible on the finished product. The finest car interiors use full-grain leather in its natural form, cutting out any sections with blemishes or scarring on the skin.
Less expensive car leathers keep the blemished sections intact to save production costs. Those blemishes are then sanded or buffed out, and the leather is embossed with a faux grain. This corrected-grain leather is still usually of very high quality.
Regardless of the quality of the finished product, all leathers must go through a tanning process. By far the most common tanning method for car seat leather is chrome tanning, in which the hides are soaked in a solution of chromium sulfate. Some manufacturers use vegetable-tanned leather for secondary locations like instrument panels and steering wheels. Vegetable-tanned leather is more pliable than chrome-tanned leather, but it is not as durable.

What Damages Car Leather
As it is a natural product, car leather is susceptible to damage. Some of the enemies of leather include water, ultra violet light, heat, low humidity and time. To protect the leather, manufacturers usually coat it in a thin layer of perforated vinyl. The top coat shields the leather from UV light while still allowing it to breathe.
Unfortunately, some types of leather damage are irreversible, such as water damage. In this case, water seeps into the seat between the sewn seams of the leather panels that comprise the seat. The underside of the leather is uncoated, so it absorbs the water. The resulting damage is permanent, and even the best product for cleaning leather car seats can’t help you then. Other types of damage (even small rips) may be repairable, and most of it is completely preventable. That’s where leather cleaners and conditioners come into play.
What Cleaners and Conditioners Do
Leather cleaners are liquid chemicals that liquify the dirt and grime that collects in the grain of the leather and between the seams of the panels. Once it is liquified, the dirt is easily lifted with a clean, dry cloth. Leather conditioners penetrate the surface layer of the leather, softening it and slowing the desiccation process that slowly breaks down the fibers in the leather.
How to Clean and Condition Leather Seats
Always vacuum the area to be cleaned before you begin using any cleaner or conditioner. Those little scraps of dirt and debris can scratch the vinyl coating once you begin rubbing in the conditioner. Step two is to clean the area with leather cleaner. Typically, you will apply these products liberally, then wipe off the excess. The final step is the application of conditioner. If the conditioner does not penetrate, the top coating is likely not perforated. It will break down over time, though, so try again in six months to a year.
